Hey Bool, welcome.
If you feel you may have an issue, try stopping totally, even on weekends.
For me, I didn't think about the things you originally posted until it was too late. I crossed that line over into alcoholism at some point.
The fact that you are questioning your drinking patterns is a good thing. You have the presence of mind to do something about it before you cross that line that we alcoholics sprint over without ever realizing.
Try the "no drinking at all" experiment for awhile. If you are not an alcoholic, it shouldn't be a problem.
God bless.
